Added Support for Crypto-Currencies list on Binance

[MohanVashist1]

This PR is to support Crypto-Currencies listed on Binance. With some simple modifications you can add support for more data sources/exchanges with ease.

List of changes:

• requirements.txt: Included python-binance as well as the supported packages required by python-binance
• Readme.md: Added section about how to use Binance as a data source and how to use an alternative ticker list
• crypto_list.txt: Sample list of crypto currencies from Binance
• detection_engine.py: added two new arguments; the data source and the stocks list. Data source tells the program where to go to fetch data (currently either yahoo finance(default) or binance). Stocks list is the file in the stocks folder which contains the list of tickers to use.
  - Added argument checking. Data source must be either 'yahoo_finance' or 'binance', stocks list must exist in the stocks folder
• data_loader.py
  - Added new two input parameters to data_loader.py,
  - changed how the stocks list is read by using the file indicated by the stocks_list parameter
  - added the ability to get data from the binance client
  - line 188-190 fixed bug with saving dictionary every 100 iterations. Due to the continue statements, the size of the dictionary can increase but checking if you need to save the file may not occur. Thus, I moved the statement which checks if we need to save the dictionary immediately after we add to the dictionary

This looks awesome. Just one question, did you test the program again with both stocks and crypto?

Apologies, I should have included this in the PR but yes I did test it here is the output:
For the command:

python detection_engine.py --top_n 25 --min_volume 5000 --data_granularity_minutes 60 --history_to_use 14 --is_load_from_dictionary 0 --data_dictionary_path 'dictionaries/data_dict.npy' --is_save_dictionary 1 --is_test 0 --future_bars 0

For the command:

python detection_engine.py --top_n 25 --min_volume 5000 --data_granularity_minutes 60 --history_to_use 14 --is_load_from_dictionary 1 --data_dictionary_path 'dictionaries/data_dict.npy' --is_save_dictionary 0 --is_test 0 --future_bars 0 --output_format 'CLI'

For the command:

python detection_engine.py --top_n 25 --min_volume 500 --data_granularity_minutes 60 --history_to_use 14 --is_load_from_dictionary 0 --data_dictionary_pata_source binance --stock_list cryptos.txt

Also note that I will be watching the Github issues for any problems that may arise. Also, feel free to contact me if you find anything else.
